IMPROVEMENT IN MARKING-BOARDS FOR PIN-POOLS.

Specification forming part of Letters Patent No. 165,985, dated July 27,1875; application filed May 22 1875.

To all whom it may concern:

Be it known that I, GEORGE H. DECKER, of Belleville, in the county ofEssex and State of New Jersey, have invented a new and ImprovedMarking-Board for Pin-Pool, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a front View of amarking-board for pin-pool. Fig. 2 an enlarged vertical transversesection of the same on the line 0 c, Fig. l,showing the construction ofthe plug containing the numbered ball, and Fig. 3 is a perspective viewof the plug detached.

Similar letters of reference indicate correspondin g parts.

My invention relates to such an improvement in marking-boards forpin-pool that the numbered balls may be readily and conveniently takenout without the annoyance of dropping the same on opening the slidegatesor hinged caps at present in use.

The invention consists in recessing the marking-board for the round orotherwise shaped plugs that contain the balls securely in concaverecesses.

In the drawing, A represents a markingboard for pinpool, which isprovidedwith as many round, square, or otherwise shaped recesses a asthere are balls used. The recesses a are bored or cut into themarking-board, and closed by correspondingly-shaped plugs B, which areinserted therein and taken hold of by num:

bered buttons B, made in one piece therewith.

An outer flange, b, of each button, defines the extent of sliding motionon putting it into its place. The position of the round plugs may besecured, if desired, by means of side tongue and groove, or by aretaining-spring. Each plug B has at its upper part a spherical recessor concavity, d, for a ball, having the same number as the button. Theball may also be retained by concaving the rear side of the plug andattaching two band-springs at opposite sides, that clasp the ball andretain it in position. I prefer, however, the recessed plug, on accountof its greater simplicity. The ball is placed into the recess of theplug, and inserted and taken out with the plug to be easily dropped outof the cavity by merely turning the plug, being conveniently replacedand reinserted with the plug, Without the annoyance incidental to thepresent construction of the marking-boards.

Having thus described my invention, I claim as new and desire to secureby Letters Pat ent 1. A marking-board for pin-pool, provided witha'series of recesses, in combination with numbered plugs fittingtherein, having cupshaped cavities for the balls, substantially as andfor the purpose set forth.

2. A plug for marking-boards, provided with. button, face-flange, andcup-shaped recess for the ball, substantially as set forth.

Gr. H. DECKER.
